Jeremiah95

So I’m new to the Honda tech forums but have read sum helpful articles but I just bought a 1995 eg sedan with a b18b1 with p75 ecu the guy I got the car from said it has arp head studs and aftermarket clutch and is tuned for all motor but it dropped a valve and sent the piston through the front of the block it came with a b20z2 that set with no plugs so it has rust on the cylinder walls I got the rust off as best as I could but the pistons are seized I took head and oil pan off to see if the was any thing keeping it from turning over but I didn’t see anything so I tryed tapping the top of the pistons with a 2x4 and trying to turn it over with a breaker bar but it wouldn’t budge so i figured put everything back together drop it in the car and see if the starter will break it free that don’t work I was just gonna rebuild the bottom end the head looked a little rough from setting but it didn’t have any major rust or anything just needs cleaned up but if I can’t get it to break free I was gonna rebuild it and take the arp head studs out of the b18b1 and put em in in a the b20z along with intake manifold and trans with the p75 ecu but I don’t know if I’m on the right track or how should I go abt it
